SASH-BALANCE.

SPEGIFIGATION forming part of Letters Patent No. 445,376, dated January 27, 1891.

Application filed October I, 1890. Serial No. 366,796. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH P. MAGNEY, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain newand useful Improvements in \Vindow-Sash Balances; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

My invention has relation to certain new and useful improvements in window-sashbalances; and it consists of the arrangement of parts and details of construction, as will be hereinafter more fully set forth in the drawings and described and pointed out in the specification.

The object of my invention consists in obviating the use of sash window-weights for raising and lowering of the sash, and at the same time allow for the holding thereof in adjusted position by frictional contact of the hereinafter-described actuated roller.

My invention consists in providing a frictional spring-actuated roller, which shall be simple of construction, more effective in its operation, and less expensive than any device of a similar nature heretofore known to me.

Referring to the drawings forming a part of this specification, wherein similar letters of reference are used to denote corresponding parts throughout the entire specification and several views, Figure 1 is a front viewof the window, showing the casing partly broken away for better illustrating the position of the bearing-roller; Fig. 2, a longitudinal sectional view of the bearingroller, showing same within its holding-frame; and Fig. 3, a front view in elevation.

The letter A is used to represent the metallic frame, which is provided with the extending shoulders a, having openings a formed therein, by means of which it is secured within the window-casing A. Said frame has its front end opened sufficiently to permit the bearingroller to enter. The inner side faces thereof have guideways 1) formed thereon, clearly shown in Fig. 3.

The bearing-roller is indicated by the letter B, which revolves upon axle b, secured by means of brace B. The outer periphery of said bearingmoller is provided with a tire of rubber or other suitable material, as indicated by 12 in order that greater friction may be obtained. 5 5 One face of said roller is countersunk and has located therein the coil-spring O, which is fastened to the wall thereof by means of pin 0 and to axle b by pin 0. In order to permit of the insertion and removalof the bear- 6o ing-roller, I provide the connecting-brace with circular openings cl on each side of larger diameter than axle Z), and which terminates in an elongated opening d of equal diameter therewith. After inserting ends of axle b within the circular opening d the same is moved or pressed into elongated opening cZ, wherein it is retained until thrown forward into circular opening d of greater diameter. Inasmuch as the axle is stationary, the roller rotating thereon, it is obvious that no wear of the opening takes place.

The bearing-roller is secured within the frame A by means of the connecting strap B, which works within the guideways b of said casing, and said bearing-roller is kept continually pressed outward by means of the spring D, located at the rear of the frame, and which bears against the rear of strap B. As will be noticed by reference to the drawings, the periphery of the bearing-roller projects beyond the casing, so as to bear tightly against the window-sash, and is maintained in such position by means of the spring D. The coil-spring O is sufficient in length to allow for the rotation of the bearing-roller during the entire upward or downward move ment of the sash. In practice I shall employ four bearing-rollers-two for the upper and two for the lower sash-which shall be so 10- o cated as to bear against the same frame when raised or lowered their full length. By thus locating the rollers to each side of the sash I provide a uniform pressure thereon, thus obviating swagging thereof. 5

I am aware that minor changes may be made in the construction of parts herein shown and described without necessitating or creating a departure from the nature and scope of my invention. IGO

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent of the United States, is

1. I11 a window-sash holder, the combination of a frame provided with an opening at its inner end and guideways upon its inner side faces, a U-shaped brace fitting in said guideways and having its ends at opposite points provided with circular openings comm unicat ing with smaller elongated openings, a transverse shaft having its ends normally fitting in the elongated openings, and a spring actuated and rotatable bearing-roller upon said shaft, substantially as set forth.

2. In aWindoW-sash holder, the combination ways and provided upon its ends, at opposite points, With circular openings terminating in smaller elongated openings, a shaft having its ends normally fitting in the elongated slots, a roller mounted upon the shaft, and a spring having its free ends bearing against the brace and adapted to press the roller inward, and at the same time keep the axle Within the elongated slots, substantially as set forth. 1

In testimony whereof I afiix my signature in presence of two witnesses.
